We don’t call our cousins cousin Somebody the way we do with uncles and aunts; we just refer to them by their given name directly.
But sometimes we cannot use their name to address them, such as if they are older than we are, so then we refer to them as brothers or sisters.
One of my cousins, who is older than me, recently got married. What is the appropriate way to call his wife in this case? Calling her my cousin-in-law is little embarrassing to me, so I would like a word that does not embarrass me.
